Both are inter- nally connected, so not operational at the same time. The electronic input stage is built in a servo balanced design which handles monau...

User's guide adi-8 ds © rme 11 6.5 word clock input and output input the adi-8 ds' word clock input is active, when ext is chosen in the clock section (see chapter 7, clock section). As soon as a valid signal is detected, the ext led is constantly lit, otherwise it is flashing slowly. Thanks to rme'...

14 user's guide adi-8 ds © rme the tdif format is especially critical with respect to word clock. We have mentioned this in different places of this manual: when the adi-8 dd is slave no additional word clock connection is necessary. In case da88 and/or da38 are slave the word clock output of the ad...

To use the complete dy- namic range of the adi-8 ds with such devices the functions bit split and combine were integrated. This technique is a simple but effect...

When copy mode is active the digital input signal of the da-converter...

User's guide adi-8 ds © rme 17 9.4 dither thanks to bit split and combine the adi-8 ds preserves full 24 bit resolution even when working with 16 bit devices. It may happen that the actual recording situation does not allow a usage of bit split/combine. When using double speed (88.2 and 96 khz) bit ...
